Colbert's interview with Uber CEO interrupted by protester

Stephen Colbert's interview with Uber CEO Travis Kalanick for Thursday's "Late Show" came with an unexpected twist: a protester.

The high-profile interview was briefly derailed when a man, seated in the balcony of the Ed Sullivan Theater, interrupted to say that Uber is "destroying full time professional taxi jobs," according to an audience member.

Kristin Condon, a guest who was seated in the orchestra section, said that the crowd reacted with "stunned silence."

Condon added that Colbert let the protester speak, and didn't kick him out of the taping.

"He was angry, but he wasn't obscene," Condon said of the protester. "It was also interesting that Colbert was really respectful... and allowed it to be an issue rather than just silencing it."
